V. Scotti, University of Arizona, reports his recovery of comet P/2007 C1 (cf. IAUCs 8805, 8808) on CCD images obtained with the Spacewatch 1.8-m reflector (+ Finger Lakes ProLine Model PL3041-LC camera + Schott OG-515 filter; bandpass 515-950 nm) at Kitt Peak. The comet appears essentially stellar (noobvious cometary activity) on all the images, and his astrometry is tabulated below. 2014 UT R.A. (2000) Decl. Mag.
